hesive coated strip for application to various objects, such as leather composition, etc., in the manufacture of footwear.

The objects of the invention include the provision of a simplified apparatus for applying a substance to, a moving web; the provision of a guide for the web, power driven rolls for feeding the web from a supply source along the guide, and then guiding the web about certain of the driven rolls, another driven roll serving to conduct the substance from a reservoir to apply it position to leave the whole machine open for adjustment or other purpose; the provision of a device which will advance the art of cement, paste, etc. applying particularly for, but not limited to, the manufacture .of footwear.

Other objects and advantages of the invention will appear hereinafter.

Reference may be had to the accompanying drawing, in which Fig. 1 is a plan view of the device; Fig. 2 is a side elevation of the device as seenin the direction of the arrow 2 in Fig. 1;

Fig. 3 is a detail view of one of the rolls and its driving connection to a power source; and

Fig. 4 is a sectional View taken on the line 4-4 of Fig. 1.

In the drawing the numeral l denotes a table or supporting frame upon which the entire apparatus is mounted. From a convenient part of the table Hi there is a bracket [2 extended to rotatably mount a roll of duck cloth l4. Obviously, however, any material which lends itself to web feeding may be processed instead of duck cloth. The web 46 is taken off the roll l4 and delivered to an elongated inclined platform l8 The web is held against the platform by a pivoted weighted roll 22, and is conducted up the'inclined platform between the flanges over the end of the platform which is bent over, down and part way around a shaft or rod 24, which is thus mounted on the end of the platform. The web then passes below this shaft 24 and over and part way around a metal roll 26; this roll being rotatably mounted on an element to be described below. Passing partially about the roll 26 the web is transferred to pass over a roll 28, thence vertically downwardly through a hole in the table 10 to the floor, whence it is drawn by the operator, to be pasted over a shoe sole, or to whatever the web is to be applied.

As clearly shown in Fig. 2, the inclined plat- 5 form [8 is swingingly mounted to pivot about an edge of the table Ill, as indicated at 30. Adjacent the edge 30 there are provided two spaced supports 32 extending up a short distance from the surface of the table In. These supports provide a journal for pivoted roll-carrying arms 34, forming a frame, which extends from the journals upwardly and then forwardly, as shown in Fig. 2. Adjacent the end of the frame opposite to its journals there are mounted the brackets 36 which in turn support the shaft or rod 24 in connection with the platform I8. brackets33, the arms 34-have journaled therebe- Adjacent the 1 tween the two rolls 26 and 27 in fixed and substantially contacting relation to each other, and the extreme forward ends of the arms 34 carry handles 38. Since the rod 24 is mounted on the platform 18- and on the frame 34, 34, it is clear that if the frame is swung upwardly about its 5'- journals on supports 32, the platform must also swing upwardly about its pivot point 30. This action is clearly illustrated in Fig. 2, therein it is shown that the platform I8 also moves somewhat away from the rolls 26 and 21 because of the rela- 30- tive spacing of the pivot points of the platform I8 and arms 34.

The roll 28 is provided with a plurality of spaced knurled ribs 40, and is journaled in supports 42 on the table II], through shaft 44 to which and drives the same, when meshed with gear 46. 5

The gears 48 and 50 are housed in a casing 52 secured to the adjacent arm 34.

The roll 28 and gear 46 are driven by the motor 54 through a reduction gear in housing 56, both motor and reduction gear being mounted on the 50 table 40. Between the reduction gear-and the gear 46 there is a break-pin connection 58 to disconnect the motor in case of accident.

The cement, paste, or other substance to be applied to the web [6 is contained in a known ,55

type of reservoir 60, and flows through a channel 62, which has an offset portion 64, into which the roll 21, extends when in operating position, as shown in Fig. 4. At the end of the offset portion 64 next to the roll 21, the channel is provided with an upwardly extending element 66 which bears against the surface of the roll 21 and scrapes the same to spread the cement, paste, etc. evenly. This edge 66 may be inclined to the bottom of the channel 62, or beveled, .or merely vertical, as shown. The cement or paste reservoir 66 is supported on the: table ID by a bracket 68.

In the operation of the device, the roll of duck cloth or other material is placed in proper position on the bracket 12, and the web [6 is conducted up the inclined platform l8, down about the rolls, 26, 28, thencedown to the floor, as previously explained. The cement, paste, or other substance flows at a constant rate to the offset channel portion 64, where it is picked up by the roll 21, scraped and evenly spread thereon by the element 66, and transferred to the contacting roll 26. As the cloth or other material passes around the roll 26, it is covered on one side with the substance, as is clear. Although the web is covered with the substance, some of the latter is absorbed by the cloth so that a fixed coating is not necessarily formed.

The table l6, reservoir 60, channel 62 and roll 28 are stationary, but the arms 34, together with the rolls 26, 21, maybe raised about the journals in supports 32 upwardly to dotted line position, as shown in Fig. 2, and this leaves the whole machine open for adjustment or any changes the operator may wish to make.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a device of the class described, a platform for guiding a web mounted to rest on and slide over a support, a frame pivoted on the support and carrying a web-guiding roll at its free end, the platform and frame being pivotally connected adjacent the roll, whereby the platform is swung upon pivoting of the frame.

2. In a device of the class described, a driving shaft, a gear and a roll on the shaft, a pivoted frame having a shaft journaled therein, a second gear and a second roll on the latter shaft, the

gears meshing and the rolls being in surface contact in one position only of the pivoted frame, a reservoir having a side wall, a third roll on said frame and having a gear constantly meshing with said second gear, and said second and third rolls being in constant contact, said third roll and said second roll being on opposite sides of said wall when the frame is in said one position.

3. In a device of the class described, a driving shaft, a gear and a roll on the shaft, a pivoted frame having a shaft journaled therein, a second gear and a second roll on the latter shaft, the gears meshing and the rolls being in surface contact in one position only of the pivoted frame, a third roll, journaled on the pivoted frame, in surface contact with the second roll, a third gear for driving the third roll, in constant mesh with the gear for the second roll, whereby the driving shaft drives all three rolls in one position of the frame, and in another position thereof, only the first roll is driven, and a fixed reservoir located so as to receive said third roll only when the pivoted frame is in said one position.

4. In a device of the class described, a support, a frame pivoted to said support and carrying a web-guiding roll, a web-guiding platform pivoted at one end to said frame and having its other end slidably resting on said support whereby said platform is swung upon pivoting of the frame.

5. In a device of the class described, a support having an edge, a bracket extending laterally below said edge and adapted to carry a web, a frame pivoted on said support adjacent said edge and carrying a web-guiding roll, a web-guiding platform pivoted to said frame adjacent said webguiding roll and having a portion freely slidable on said edge, said web extending from said bracket over the platform and about said web-guiding roll.

6. In a device of the class described, a support, a frame pivoted on said support and having a web-guiding roll mounted thereon in contact with an applying roll, a reservoir to receive said ap-
